Hmmmm, I'm looking at rebuilding my bike and at least part of that involves new stem, handle bars and seat post. As such, I'm just curious as to the science of bike geometry and positioning of parts on the bike to be most efficient, powerful and comfortable (you know when these guys take your measurements and custom build frames, what are they doing with the measurements?).

Is there any good resource that explains this at length???

I know a few basics, like leg extension and how your knee should be over your pedal at the front of its stroke. But other finer details probably elude me.

How does body positioning/frame geometry differ for road, mountain and touring?

Thanks in advance

Matt:

This might help. It isn't a book but a fascinating article. It dispells the high saddle low handlebar myth everyone seems to have. https://www.nettally.com/palmk/BikeFit.html
